JEAN ALE SPECIFICATION forming part of Application filed March 14, 1901.Sari To all whom it may concern:

Be it known that I, JEAN ALEXANDRE LA- GGTE, a citizen of the Republicof France, and a resident of Paris, France, have invented a new anduseful Improvement in or Relating to Machines for TreatingVegetable-Stems, which improvement is fully set fort-h in the followingspecification.

The present invention relates to a new machine for stripping andpreparing vegetable stems, such as ramie-stems and the like, preparatoryto spinning.

In order to render the following explanation as clear as possible, amachine according to this invention is represented in the accompanyingdrawings.

Figure 1 is a part-sectional view in elevation of the machine, one ofthe lateral brackets being removed in order to show the inte- Fig. 2 isa plan view of the machine. Fig. 3 is a side view showing the riorparts.

driving-gear.

The machine comprises twogrooved rollers The upper roller ct is mountedin movable bearings l), which can be adjusted by The object of thisarrangement is to vary the distance between means of screws 0.

the two rollers Ct at.

The vegetable-stems are introduced into the machine over the plate orguide cl and pass between the two grooved rollers a a, which in carryingthem forward break the wood in the interior of the skin of the stemsinto small pieces without, however, breaking the external longitudinalfibers. stems pass between grinders or rubbing de Each of these devicesconsists of two end plates with four radiating arms f. The arms of oneof the brackets are connected to the corresponding arms of the otherbracket by means of rods g, provided with vices e e.

a loose sleeve or tube of much greater internal diameter than the XANDRELAOCTE,

Thence the h, which sleeves are diameter of the rods g, so as to hangloosely thereon and to be pressed laterally relatively to the rods bythe action of the stems passing between the rubbing devices. The sleevesLetters Patent No. 701,057,

' h of one of the devices Fig. 1, between two arms of the other grinder,so as to intercalate, and the devices having opposite rotatory movementsthe sleeves 7L grind or rub against the vegetable-stems as they rotate,detaching thereby the fragments of broken wood produced by the action ofthe In this way sliders or or stems are obtained, the ligneous partshaving been completely removed.

The transmission of m in the following manner: ed upon a shaft j,carrying a sprocket-wheel r which a chain 1 passes, which transhemovement to a pinion m, the shaft of the inner grinder e. extremity ofthis shaft is a spur-wheel 0, which engages with a wheel 19, fixed onthe shaft of the other grinder 6, thereby efiecting the oppositerotation. of Moreover, a toothed wheel (1 is keyed on the main shaft j,which engages with a wheel 0, mounted upon the shaft 3 of the innerroller a. This shaft 3 carries at one of its ends a toothed wheel to,which engages with a wheel a, ed upon the shaft of the other roller a,thus producing the opposite movement of the two grooved rollers a 0/.

Having now particularly described and ascertained the nature of the saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is In a machine for treating vegetable-stems, a pair ofoppositely-revolving rubbing d constructed of radial arms connec byparallel rods, and tubes or sleeves of rather greater internal diameterthan the rods, and hanging loosely on the same so as to have a certainlateral motion relatively to the rods, substantially as set forth.

In testimony whereof I have signed this the presence of two s rollers a0..
